BOX-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 619,809, dated February21, 1899.

Application led March 8, 1898. Serial No. 673,071. (No model.)

To all whom it may concern.:

Be it known that I, JOHN UNSER, a citizen of the United States, residingat Carthage, in the county of J eerson and'State of New York, haveinvented certain new and useful Improvements in Box-Fasteners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention has relation to fasteners for boxes.

The object of the invention is to provide a fastener for locking andsecuring the bottom, sides, ends, and cover of the box together.

With these objects in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a front elevation of the box,showing my improved fastener engaged therewith. Fig. 2 is a verticalsectional view. Fig. 3 is a view of the fastener about to be applied.Fig. 4 is a similar view of the fastener applied, and Fig. 6 is asimilar view of the rotary bolt extending through the sleeve of thefastener.

In said drawings, 1 denotes a box consisting of a body portion 2, whichforms the back and cover. The portion 3 is bent to form the bottom andfront and the ends 4, having flaps 5, which are adapted to be broughtaround parallel with and behind the front of the box. These iiaps andthe front of the box are provided with registering holes 6, and thelower edge of the cover of the box is provided with a keyhole 7.

8 denotes a plate having a tubular extension 9 formed with slots 10 toprovide spring-arms 11, having integral humps 12. This tubular extensionis inserted through the holes of the iiaps and front of the box, and thespring-arms are compressed togetherto permit of a washer 13 beingslipped over the humps on the arms, when the arms will spring outward,thus securely holding the washer in place.

14 denotes a bolt that is inserted through the tubular extension and isheld in place by a @otter-pin 15. This bolt has an angular arm or handle16, which after it passes through the keyhole in the cover is adapted tobe turned down to lock the cover in place. The bolt has an additionalfunction-namely, that of holding the spring arms outward, and therebypreventing them being compressed and allowing the washer to slip 0E.

While I have shown the fastener applied to the box illustrated in thedrawings, I would have it distinctly understood that it may be appliedto any other form of box now in use in which it is desired to hold thehinged cover to the body of the box.

Although I have specifically described the -construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

A fastener for boxes, comprising a plate having a tubular extensionprovided with slits to form spring-arms having humps, a washer slippedover said spring-arms to a point at the rear of said humps, a boltextending through said tubular extension, and preventing the compressionof said arms and thereby the accidental displacement of said washer,said bolt having an angular arm, and means for preventing the withdrawalof said bolt from said tubular extension, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

JOHN UNSER.
